Portfolio Size and Lifecycle Asset Allocation in Pension Funds
No full textLifecycle funds offered by retirement plan providers allocate aggressively to risky asset classes when the employee participants are young and gradually switch to more conservative asset classes as they grow older and approach retirement. This approach focuses on maximizing growth of the accumulation fund in the initial years and preserving its value in the later years. This paper simulates terminal wealth outcomes under conventional lifecycle asset allocation rules as well as those given by contrarian strategies that reverse the direction of the switching of assets. Our evidence suggests that the general increase in portfolio size as one approaches retirement is significant from an asset allocation perspective. Due to this portfolio size effect, we find the terminal value of accumulation in retirement account to be critically dependent on the asset allocation strategy adopted by the participant in later years (relative to earlier years). By investing conservatively in such crucial phase, lifecycle strategies recommended by financial advisors sacrifice significant growth opportunity and prove counterproductive to the participant’s wealth accumulation objective. This does not seem to be compensated adequately in terms of reducing the risk of potentially adverse outcomes
Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Get PDF“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Get PDFWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Dispelling the Myths Behind First-author Citation Counts
Get PDFWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used
The impact of new equity financing on firms' investment, dividend and debt-financing decisions
No full textInvestment, dividend and external financing decisions are the major decisions of a firm. External financing includes the flotation of new common shares and/or new debt. Previous studies on the interrelationships among these three decisions precluded new equity financing in their models. Thus, their models were misspecified. This thesis explicitly incorporates new equity financing into the model by using a two-stage switching regression model to analyze the interactions among investment, dividend and debt financing decisions given the impact of new equity financing. Unlike the previous studies using American data, this study does not reject MM's independence theorem on the relation between the investment and dividend decisions of the firm. However, there is strong evidence that capital structure does affect the investment decision of the firm. Furthermore, this thesis provides evidence to reject John and Williams' (1985) dividend signalling theory. A pecking order theory by Donaldson (1961) and Myers (1984) is supported during the recession 1978 to 1982, but rejected during the prosperity period 1983 to 1987. There is also strong evidence of dividend smoothing for firms.Made available in DSpace on 2011-05-07T13:29:48Z (GMT). No. of bitstreams: 2
